Casey Energy's service staff have always been professional, knowledgeable, and punctual in providing service calls to our home. We have used Casey for the 22 years we have lived in our home to service our oil burner. Just recently, we signed with Casey to service our Central AC system and it came in real handy last week when the condenser stopped working. Hal, the Casey service tech, came to our home in the evening (within an hour of calling back) to check out the unit and with darkness looming, was back at our home first thing the next day. Hal was able to determine that the unit was losing freon and, after doing some testing, found the source of the leak. Hal plugged the leak, tested the lines and refilled the system with freon. Now our AC system is working as good as new........I highly recommend Casey Energy and Hal the service tech for servicing your AC system.
